Product Information

The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Air stays put safely. It also helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection.

When the connection is secure, an LED located at the head of the DC connector lights up; an amber light lets you know that your notebook is charging, while a green light tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.

Designed to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage.

This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery.

Compatible only with MacBook Air featuring MagSafe 2 power port.

Not sure if this is the right power adapter for your Mac?

Knowing which specific Mac model you have is important. If you are running OS X Lion (10.7) or later go to the “” menu at the top left of your screen, choose “About this Mac” then click the “More Info...” button. Your Mac model and generation will be displayed.

If you are running an earlier version of OS X, you can enter your serial number here to find out which model you have.

Broke too soon

Quite careful with my equipment. This one simply stopped working under no significant stress conditions. Quality control alert.

This is like a bad dream. When I saw the reviews I thought they were joking. I feel like sending the entire laptop back because of the adapter. It falls off for no reason and gets in the way. Apple needs to do a recall.

Only read reviews of MagSafe TWO - it's TERRIBLE!

All these reviews saying they've had no problems for over 6 months are reviews for other models. The new MagSafe 2 hasn't been available for that long - only since the new 2012 MBA's came out in mid-June. The new MagSafe 2's charger attachment magnet is incredibly weak and will detach at the slightest provocation. Or unhappy thought. Or suspicious look. This product is terrible and Apple should fix this as soon as possible.

I bought my Macbook Air almost a week ago ... I love love love it. As I am here to rate the power cord, I will say that is is working fine, so far. I used it for the first time this morning and my computer charged with no issues at all. The magnetic part seems to stick pretty good ... at least for today it does. I have read a lot of these reviews and I am worried. I thought about buying another one, but don't think I will now. I'll make due with the one I have. The only thing I can think of is my Macbook Air is the new one that came out, meaning they made improvements to the processor (1.4 vs 1.6) ... maybe they also made enhancements to the power cord.

I purchased this MacBook pro with retina display 2 days ago and have been frustrated at the power cord constantly falling out! I also had it plugged in all last night to find that my machine was only 80% charged this morning! Why are you suddenly creating such an inferior product? don't you test them any more before putting them on the market?- You are really upsetting your customers.

You should do put every available engineer on this problem until it is fixed; do a recall, and show that you deserve your customers' trust.

I am very very very disappointed.
